Facial width-to-height ratio
Cheekbone-to-cheekbone width divided by the height of the upper face. It is the most studied single ratio in face perception research, and also the most over-read one.

Also called fWHR, bizygomatic width to upper face height.
Reference range
None.
We have not validated a population reference interval for this photographic method. Published anatomical measurements do not automatically validate mesh-based estimates.
How we calculate it
Width is the distance between the left and right cheekbone landmarks. Height is measured from the brow line down to the top of the upper lip. Both come from the same roll-corrected mesh, so the ratio is unitless and independent of how large the face sits in the frame.
What moves the number
Weight change, which alters soft tissue over the cheek, and camera distance, which stretches or compresses apparent width. A wide-angle selfie and a photograph taken from two metres away will not agree.
What it cannot tell you
The research that made this ratio famous links it to judgments about behavior, not to attractiveness, and those findings are contested. It cannot tell you anything about a particular person’s temperament, and we do not present it as if it could.

fWHR is the most studied single ratio in face perception research. Almost none of that research asked whether a face was attractive.
